So, I missed that the original reporter was using "make" to
build. Which indicates he has an archaic version of systemd he wants
to build. We cannot retroactively update those.

As it turns out since a long time, more current versions already have
a meson check for this, and use the right type depending on the gperf
version you are using.

Hence, there's nothing left to fix, upstream already auto-detects
everything, just upgrade your systemd tree. (or downgrade your build
chain…)
